approval of the PMC and or RVNL. The Contractor will submit Request For Inspection (RFI) to

PMC for inspection with an unique number at least 24 hours prior to actual execution of work.

An advance statement (RFI Summary) through email with tentative works or activities to be

executed against production of RFIs will be sent to PMC daily. Copy of the RFI Summary and

photocopy of RFIs duly numbered will be sent to the PMC.

The day to day work approval System is based on two main factors.

Request for Inspection to Proceed Request for Approval on completion.

1.7 REQUEST FOR INSPECTION TO PROCEED AND FOR APPROVAL

In this Project, a comprehensive form has to be developed clubbing Call for inspection and

approval on completion for allowing proceeding with next stage of Execution especially in Railway

bed. This form submitted by the Contractor must be used in every case where a Quality controlled

task intends to start. The form must be duly signed and dated by the Contractors representative and

all the experts of the PMC and the Client have the opportunity to comment at inspection time.

RFIs are submitted in triplicate along with one set of standardized checklist. Formats for checklist

for different elements of work must be carefully prepared covering all the minute details of work as

per standard Engineering practice and approved method statement. The PMC must have to record

their observations against each query in the checklist. Findings of inspection are summarized on the

basis of test as per Construction requirements and recorded in the RFI. The PMC Expert finally

signs the form by either approving or rejecting the work according to the net result of inspection.

The works shall execute once the PMC approves. In turn PMC, as per their matrix of reporting will

provide information / copies to Client. The PMC will return copy of RFI, checklists and approvals

to the Contractor and Contractor will attach the same with Running Account Bills for the quantities

and works executed claimed in the Running Account Bill.

Quality and Safety Plan (QSP)

CHAPTER 2. QUALITY CONTROL PROCESS

The basic concept for production of a quality work is illustrated in the model below:

The main inputs for a Railway project to perform are Men, Materials, Machineries, Money and

Time. The documents specify the materials, their qualities and acceptance criteria for their use.

Process control specifications are usually incorporated in the contract documents. These specify

the functional requirements of the machinery or equipment to be used in the production process.

The Contractor normally establishes the other controls viz., money and time. The PMC usually

approves the time input factor and accordingly recommends the technology of production. The

periodic checks during construction process are carried out as laid down in the various codes and

specifications mentioned there in both by the Construction Contract and the Consultant Contract.

The application of these activities would eventually assure a quality product at the end. A quality

control plan for each activity shall be submitted at least 21 days prior to the start of the activity by

IVRCL to PMC which consists of properties of materials, construction procedure, equipment,

inspection plan along with responsibility matrix, test plan along with reports to be generated, etc

CHAPTER 3. QUALITY CONTROL DURING CONSTRUCTION

3.1 Quality Policy

The quality policy of PMC is based on dedicated commitment to implement quality assurance to

deliver a product conforming to specifications and standards. The aim is to deliver consistent

quality product to the satisfaction of the client.

3.1.1 Request for Inspection (RFI)

This composite form, submitted by the Contractor, must be used in every case where a quality

control task intends to start. This form must be duly signed and dated by the Con tractors

representative and all Engineers associated with that particular activity at specified location have

the opportunity to comment during inspection. The Expert of the PMC will inspect the execution

process, test and ensure the task has been completed to the standard required and write comments

to that effect. The form must be duly signed by the relevant Engineer. If there are negative

comments, then the representative of the Contractor will be informed of the same with the

direction to rectify or redo the work and to raise fresh RFI for further inspection after necessary

correction. After successful completion of task the representing engineers of PMC shall sign for

its acceptance and return the copy to representing Contractors Engineer.

3.1.2 NonConforming Reports (NCR)

The purpose of NCR is to establish how to control nonconformity to specific requirements, and to

prevent such material from unintended use or installation. If the construction activities carried out

by contractor at site are not conforming base on QA/QC Plan and/or construction drawing, the

required corrective measure should be instructed to the field engineer at site for corrective action

of particular items. If the instruction given by the PMC is overlooked in such incident, Non

conformity of such work should be issued to the contractor. The contractor should take

immediate action by repaired or reworked, which are taken cause of nonconformity. If necessary,

to implement the corrective action to eliminate the cause of nonconformities and to prevent

recurrence shall be established.

3.2 NCR (Explanatory Note)

1. Engineers by means of NCR shall report problems, defects or deficiencies identified duringconstruction.

2. NCR shall be raised for problems defects or deficiencies encountered in the following areas: -

well equipped and properly calibrated site test laboratory is therefore an important element of

quality control. The Contractor is required to set up the site laboratory before commencement of

construction activities.

A list of testing equipment provided by the Contractor for the site laboratory is to be submitted to

PMC. As per suggestions of them, testing equipments are to be added or modified including their

orientation. PMC will give final approval to the arranged facilities of the laboratory. Laboratory

equipment shall be properly calibrated and calibration certificates will be kept at the laboratory.

Specialized tests at outside independent laboratories shall be undertaken as per instruction of

PMC. The details of input materials should be recorded in Material Register.

Page 21 of69


3.5 SITE INSPECTION

Site inspections are to be carried out to ensure that the materials and construction activities

conform to the prescribed standards. Site inspections can be divided into day-to-day supervision

and periodic site visits.

The Contractor shall give advance notice to the PMC when critical activities are proposed to be

undertaken and when a stage of work has been or is expected to be completed. On completion of

a stage and before proceeding to the next stage, the PMC shall inspect the quality of the works

executed. The final inspection shall encompass tests on completion as specified in the contract

documents. The certification of quality will be based on test reports and site inspection.

3.5.1 Equipment:

Construction equipment is a major component of quality and Safety system. It is necessary that

the PMC check the adequacy of the equipment used by the Contractor for construction as per the

standard and special specification or his appointed Sub Contractors will from time to time, check

the calibration of equipments as necessary. It would be also be necessary to record the equipment

used for construction in the daily logs describing the condition of equipment, no. of hours used

for the day for execution of works including item of work done in brief. PMC will periodically

inspect the equipments and advise for compliance.

CHAPTER 4. QUALITY CONTROL PROCEDURES

4.1 Earth work

a) Frequency of testing at site: At least one test at every change of soil strata subject

to minimum of one test for every 5000 cum to assess suitability of fill material and to lay

down OMC and MDD / Relative Density.

b) Method of test: Fill material shall be tested to ascertain its suitability as per the test

procedure format.

c) Acceptance criteria: Materials conforming to Para 5.0 of RDSO Guidelines for

earthwork in Railway Project need only to be used for construction of embankments.

In addition the soils having classification CH or CI or having lower MDD than 1.7

gm/cc will not be permitted.

4.2 Blanket Materials

a) Frequency of Tests at site: Minimum one test per 500 cum or part thereof.

b) Method of Test: Blanket material should be tested as per IS: 2720 (Part4) to plot particle

size distribution curve, so as to assess its suitability. It would be necessary to carry outwet analysis to assess actual percentage of fines. To expedite testing work, dry sieve

analysis may be carried out if variation between results of dry and wt analysis are not

significant and adequate margin exists with respect to acceptance criteria. However, in

such cases also, wet analysis has to be carried out at frequent interval to verify the extent

of variation. In any situation, acceptance of blanket material would be based on wet

analysis only. The sample for wet analysis should be prepared as per Para 4.3 of IS :

2720 (Part4)

c) Acceptance Criteria: The material should generally conform to specification as given in

RDSOS Guidelines for Earthwork in Railway Projects (Para 4.3.4). However, even if

the gradation of the soil is not falling within the enveloping curve but are having MDD

minimum 1.9 gm/cc, will be accepted for blanketing.

4.3 Quality Control Checks on Finished Earthwork

Compacted Earth: To assist the contracting agency for routine test for degree of compaction of

earth layer of compacted soil at locations selected in specified pattern. Carrying out periodic test

checks to ascertain the embankment constructed as per specified compacts efficiency.

7/30/2019 QSP 19-10-12

24/69




Page 23 of69


a) Method of sampling

Various method of selection of sample points for check of in-situ dry density are in

vogue. The sampling adopted has to be such that effectiveness of proper compaction

having been done for the entire area under consideration can be judged. For this, the

Engineer-in-Charge should lay down the method adopted in detail depending on site

conditions and accordingly records of checks done are properly maintained. However, in

absence of such procedure laid down, following method should be adopted.

Suggested Method of Sampling : For each layer, a minimum of one sample at a

predetermined interval (In compliance with the requirement stated in next para) along the

centerline of the alignment, would be taken in a staggered pattern so as to attain a

minimum frequency of tests as given in the RDSOs Guidelines for Railway Project Para7.2.2.1 (b). For subsequently layer, the stagger should be such that the point of sampling

does not fall vertically on the earlier sampling points of the layer immediately below.

Additional sampling points can be taken, as considered necessary.

b) Frequency to Tests:

Frequency of test of their acceptance critters has been enclosed as format under

AnnexureI.

Formation Level: Finished top of sub-grade level may have variation from design level

by + 50 mm and finished top of blanket layer may also be permitted to have variation

from design level by + 50 mm. The ballast should be placed only on level formation

without ruts or low pockets. At isolated locations the design level may vary up to + 100

mm

Cross Slope: should be 1 in 30

Side Slopes: Side slopes should in no case be steeper than 2 (h): 1(v) bank and 1(h); 1 (v)

in cutting. Provision of berm width should not be less than the designed width.

Formation Width: Formation width for bank shall normally be 6.85m and 7.15m on

curves. For cutting the width excluding side drains shall be 6.25m on straight and 6.55m

on curves.

4.4 Execution of Formation Earth Work

Earthwork in formation in embankment shall be carried out with suitable soil from outside

railway land to be arranged by the contractor at its own cost. No borrow pits for this purpose shall

be allowed on the railway land.

7/30/2019 QSP 19-10-12

25/69




Page 24 of69


The work shall be executed in conformity to RDSO Guidelines for Earthwork in

Railway Projects 2003 (with latest amendments), which forms a part of the contract

documents.

The contractor, at its own cost identifies the soil suitable for Rly. Formation which he proposes to

use in construction of the embankment and obtain the approval of engineer for use of such said

soil.

The work of execution of earth work embankment shall be carried out and completed by the

contractor as per the approved drawings and specifications.

Execution of earthwork has to be carried out in systematic manner so as to construct formations

of satisfactory quality, which would give trouble free service. The activities and adoption of good

practices involved in execution of earthwork are covered under following headings:-

Preliminary WorksTaking of initial levels and plotting cross sections. General aspects Compaction of earth work Placement of BankFill on Bridge Approaches and Similar Locations. Drainage Arrangement in Banks and cuttings Erosion control of slopes on banks and cuttings.4.5 Preliminary Works

a) Preparation of Natural Ground : Preparation of Natural ground surface may be carried out asfollows :

b) Site clearances: Full formation width at ground level plus additional extra width of 1 m on bothsides should be cleared of all obstruction viz. vegetation, trees, bushes, building, fences,

abandoned structures etc. and thereafter it should be dressed and leveled. Depressions if any,

should be filled with suitable soil duly compacted. Finally, leveled surface should be properly

compacted by mechanical means to get a level and uniform ground surface.

c) When bank is constructed on ground having steep slope then the ground surface should besuitably benched so that mew material of bank gets well bonded with the existing ground surface.

4.6 Setting out of construction limits

Centerline of the alignment (@ 200 m c/c or so) and full construction width should be

demarcated with reference pegs and dug belling about 90 cm away from proposed toe of the

7/30/2019 QSP 19-10-12

26/69




Page 25 of69


bank. Care should be taken not to disturb the pegs during construction. Pegs should be preferably

painted for identification.

4.7 Selection of Borrow Area

Borrow area should be selected for soil suitable to be used as fill materials for embankment. Tests

to assess OMC, MDD/Relative Density need to be conducted. Areas selected for borrow

materials need to be earmarked.

4.8 Selection of Fill Material

Except for unsuitable soils as mentioned in clause 5.1 of RDSO Guidelines for earthworkin Railway Projects, any type of locally available soil can be used as a construction

material. OMC & MDD of the selected fill materials should be tested in the laboratory as

per laid down frequency.

Use of material should be planned in such a way that soil with higher percentage of coarsegrained particle is placed on the upper layers of the embankment.

4.9 General Aspects

A field trial for compaction on a test section shall be conducted on fill material to assess theoptimum thickness of layer and optimum number of passes for the type of roller planned to

be used to arrive at desired density. Procedure for field compaction trials is given in

AnnexureIV of RDSO Guidelines for Earthwork in Railway Projects for guidance.

If the soil has less than required moisture content, necessary amount of water shall beadded to it either in borrow pits or after the soil has been spread loosely on the

embankment. Addition of water may be done through flooding or irrigating the borrow

areas or sprinkling the water on the embankment through a truck mounted water tank

sprinkling system. Use of hosepipe for water need to be avoided.

If the soil is too wet, it shall be allowed to dry till the moisture content reaches toacceptable level required for the compaction.

Placement moisture content of soil should be decided based on the field trial and siteconditions. The objective should be to compact near OMC to achieve uniform compaction

with specified density in most efficient manner.

Clods or hard lumps of soil of borrow area shall be broken to 75 mm or lesser size beforeplacing on embankment.

Each layer should be compacted with recommended type of roller up to required level ofcompaction, commencing from the sides, before putting next upper layer.

7/30/2019 QSP 19-10-12

27/69




Page 26 of69


4.10 Compaction of Earth Work

Performance of the embankment would depend to large extent on the quality of compaction done

during execution. To ensure proper compaction, precautions / guidelines for this have been given

in Para 6.3 of RSDO Guidelines for Earthwork in Railway Projects 2003. This should

invariably be followed.

4.11 Placement of Back-fills on Bridge Approaches and Similar Locations

The back fills resting on natural ground may settle in spite of heavy compaction and maycause differential settlements, vis--vis, abutments, which rest on comparatively much

stiffer base. To avoid such differential settlements, while on one hand it is essential to

compact the bank fill in the properly laid layers of soil, on the other hand, the back fill

should be designed carefully to keep;

Settlements within tolerable limits. Coefficient of sub grade reaction should have gradual change from Approach to the bridge, Back- fills on bridge approaches including boulder filling shall be placed in accordance to

para 605 of Indian Railways Bridge Manual 1998. Details are given in design drawings

forming part of the Tender.

Fill materials being granular and sandy type soil, therefore need to be placed in 150 mm orlesser thick layers and compacted with vibratory plate compactors.

While placing backfill material, benching should be made in approach embankment toprovide proper bonding.

4.12 Drainage Arrangement in Banks

Drainage is the most important factor in the stability of bank/cutting in railwayconstruction. Effective drainage of the rainwater in the monsoon season is very important

to safe guard bank/cutting from failure, Railway formation is designed for fully saturated

condition of soil. However, flow of water should not be allowed along the track as it not

only contaminates ballast but also erodes formation. Stagnation of water for long time on

formation is not desirable. Therefore, drainage system should be efficient enough to

prevent stagnation and allow quick flow of water.

Drainage of Embankment: In bank, cross slope is provided from center towards end todrain out surface water. Therefore normally there is no need of side drains in case ofembankment. However, there are situations where height of bank is such that blanket layer

7/30/2019 QSP 19-10-12

28/69




Page 27 of69


goes below normal ground level. In such cases, side drains may require to be constructed

along the track at suitable distance so that tack alignment does not become channel for flow

of ground surface water.

4.13 Execution of Work

The spreading of material in layers of desired thickness over the entire width ofembankment should be done by mechanical means and finished by a motor grader. The

motor grader blade shall have hydraulic control suitable for initial adjustment and maintain

the same so as to achieve the slope and grade.

Thickness of layer is decided based on field compaction trials. However, as a good practicethickness of layer should be generally kept as 300 mm for fill materials and 250 mm for

blanket material in loose state before compaction.

Fill shall be placed and compacted in layers of specified thickness. The rate of progressshould be, as for as possible, uniform so that the work is completed to final level almost at

the same time.

The rolling for compaction of fill material should commence from edges towards centerwith minimum overlap of 200 mm between each run of the roller.; In final pass, roller

should simply move over the surface without vibration so that top surface is properly

finished.

Extra bank width of 500 mm on either side shall be rolled to ensure proper compaction atthe edges. The extra soil would be cut and dressed to avoid any loose earth at the slopes.

This should preferably be done with help of grade cutter.

At the end of the working day, fill materials should not be left un compacted. Care shouldbe taken during rolling to provide suitable slope on top of the bank to facilitate quick

shedding of water and avoid pounding on formation.

During construction of formation, there may be rainfall to the extent that rain cuts maydevelop on the surface of formation due to erosion of soil. Care should be taken that these

rain cuts are not allowed to develop wide and deep otherwise these locations will remain

weak spots. The contractor must ensure at its own cost, to attend/repair such rain cuts, as a

regular measure to the satisfaction of the Engineer.

Top of the formation should be finished to a cross slope of 1 in 30 from one end to othertowards chess/drain in multiple lines and from center of formation to both sides in single

line.

7/30/2019 QSP 19-10-12

29/69




Page 28 of69


Once the top surface of the formation has been finished to proper slope and level,movement of either empty or loaded Road vehicle for transportation of ballast, sleepers etc.

should not be permitted, as these movements will cause development of unevenness, ruts

on the surface, which will accumulate water and weaken the formation. The methodology

of transportation of P. Way materials needs to be planned properly avoiding movement on

finished formation.

In conversion/doubling/rehabilitation/projects, suitable benching of existing slope shall bedone before new earthwork is taken up to provide proper bonding material left on the

benched slope. Care needs to be taken to avoid entry of rainwater into the formation from

this weak junction; otherwise this would result in development of weak formation, slope

failure, maintenance problem due to uneven settlement etc.

At locations where the water table is high and the fill soil is fine-grained, it may bedesirable to provide a granular layer of about 30 cm thickness at the base, above subsoil

across the full width formation. The contractor shall take this factor into account while

designing the formation.

At the places where embankment materials are not conducive to plant growth, top soilobtained from site clearance as well as Top layer of borrow pit which is rich in organic

content and suitable for plant growth may be stored for covering. Slopes of embankment &

cutting after construction, or other disturbed areas, where re-vegetation is required, as for

as practicable.
